Li Xiyun always knew that in the eyes of everyone, she and Xu Zhixing were a match made in heaven. The elders of the two families have recognized this marriage since they were born, and even the neighbors are used to watching this "little lover" grow up together. It's a pity that there is only a pure brother-sister relationship between them, but they have a tacit understanding but never have a heart.
In his heart, Xu Zhixing pretended to be the school beauty Lu Zhiyou, the girl whose smile was as bright as the sun. But Lu Zhiyou only had eyes for the stern senior Pei Yuheng. She chased him from the library to the basketball court, but she never got a response.
No one knew that Pei Yuheng's eyes had been following another person - that Li Xiyun who always smiled quietly. He remembered the way she held an umbrella for a stray cat on a rainy day, the way she argued her case in a debate, and all her unknown gentleness and tenacity.
When the two elders once again planned a "chance encounter" to bring Li Xiyun and Xu Zhixing on a blind date, Pei Yuheng finally couldn't hold himself back and pulled Li Xiyun out of the restaurant in full view of everyone. "I've been waiting for too long," he said in a low voice, "Can you give me a chance?"
A youth story about misplaced heartbeats begins. How will the emotional entanglement between the four people end? When everyone loves someone they shouldn't love, who has the courage to break the closed loop of fate?
